X Filter

Score and filter collected materials for X content creation. Topics scoring ≥7 points enter the creation pool.

Scoring System (满分10分)

Criteria	Weight	Description
热度/趋势	4分	Current popularity and trend momentum
争议性	2分	Discussion potential and debate value
高价值	3分	Information density and actionable insights
账号定位相关	1分	Alignment with account positioning

Threshold: ≥7分 enters creation pool

Prerequisites

Materials from x-collect (or manual input)
User profile from x-create/references/user-profile.md (for relevance scoring)

Optional State (Feedback Loop)

If available, use persisted state to improve filtering:

State dir: ~/.claude/skills/x-create/state/
Negative samples: rejected_topics.json (SimilarityFilter)
Events log: events.jsonl (optional analytics)

If state files don't exist, proceed normally.

Workflow

Input

Accept materials from:

x-collect output - Structured material report
Manual list - User-provided topics/URLs
Raw text - Unstructured content to evaluate

Scoring Process

For each material/topic, score multiple dimensions and combine with weights.

Weighted score (recommended):

FinalScore = Σ(w_i × s_i) - NegPenalty

Where:

s_i are per-dimension scores (0..max)
w_i come from references/user-profile.md (fallback to defaults)
NegPenalty is derived from similarity to rejected topics and other negative signals

1. 热度/趋势 (Trending Score: 0-4)

4分: 当前热门话题，大量讨论
3分: 近期热点，关注度上升
2分: 稳定话题，持续有人讨论
1分: 小众话题，关注度有限
0分: 过时话题，几乎无人讨论

(Optional) 新鲜度 (Freshness)

If you can infer recency from sources, either:
- fold it into Trending score, or
- add a small bonus/penalty (e.g., +0.5 for <72h, -0.5 for >30d)

2. 争议性 (Controversy Score: 0-2)

2分: 明显争议，多方观点对立
1分: 存在不同看法，可引发讨论
0分: 共识性话题，难以引发讨论

3. 高价值 (Value Score: 0-3)

3分: 硬核干货，可直接指导行动
2分: 有价值信息，提供新视角
1分: 一般信息，了解即可
0分: 低价值，无实质内容

4. 账号定位相关 (Relevance Score: 0-1)

1分: 与账号定位高度相关
0分: 与账号定位关联较弱

Check user profile at: ~/.claude/skills/x-create/references/user-profile.md If not found, assume domains: [AI/科技, 创业, 个人成长]

SimilarityFilter (Negative Samples):

If ~/.claude/skills/x-create/state/rejected_topics.json exists, compare each candidate topic to rejected items.
If max similarity ≥ 0.85: mark as likely duplicate/low-value → strong penalty or direct reject.
If 0.75 ≤ similarity < 0.85: apply soft penalty (e.g., -2 points) and explain why.

(Implementation via script):

python ~/.claude/skills/x-create/scripts/x_state.py similarity --against rejected --text "{topic}" --topk 3

Append a machine-readable block for hooks/state ingestion:

FILTER_JSON
{
  "schema_version": "x_skills.filter.v1",
  "timestamp": "{timestamp}",
  "profile": {
    "domains": ["..."],
    "persona_style": "..."
  },
  "items": [

      "topic": "...",
      "scores": {
        "trending": 0,
        "controversy": 0,
        "value": 0,
        "relevance": 0,
        "neg_penalty": 0
      },
      "final_score": 0,
      "tier": "A|B|C",
      "reasons": ["..."],
      "similarity": {

        "matched": [{"id":"rej_xxx","score":0.0,"title":"..."}]
      }
    }
  ]
}

Execution Steps

Load materials from x-collect or user input
Read user profile for relevance scoring and weights
(Optional) SimilarityFilter against rejected topics
Score each material on criteria and compute FinalScore
Diversity adjustments (recommended):
- Apply source/domain attenuation: score *= 0.6^(N-1) for repeated sources
- Dedup per topic cluster: keep best-scoring item per cluster
Categorize: Tier A ≥7, Tier B 5-6, Tier C <5
Output report + FILTER_JSON
(Optional) Persist feedback-loop state:
- Write Tier C items to rejected set:
  - python ~/.claude/skills/x-create/scripts/x_state.py reject --topic-json '{"title":"...","reason":"...","stage":"filter"}'
- Append event:
  - python ~/.claude/skills/x-create/scripts/x_state.py event --event filter.scored --payload-json '{"accepted":3,"maybe":2,"rejected":7}'
